This application claims the priority of my now abandoned provisional patent application Ser. No. 60/547,233 filed Feb. 24, 2004.
This invention relates to an inflatable pillow. More particularly, it relates to an inflatable pillow incorporating a water compartment that can either be used over the back of a chair, or can be used in a tub in the bath or at a spa.
An inflatable beach pillow having a pocket adapted to be filled with sand and having straps to attach it to a chair is shown in U.S. Pat. No. 4,815,154 issued Mar. 28, 1989 to Grimes. The Grimes patent uses sand as a weighting material and therefore would be of limited use in a swimming pool where there is no sand.
U.S. Pat. No. 6,217,116 issued Apr. 17, 2001 to Sloot discloses an inflexible pillow attached to a pocket-shaped slipcover designed to fit over the back of a chair, but having no means to use it as a weighted beach pillow.
My U.S. Pat. No. 6,684,429 issued Feb. 3, 2004 describes a beach pillow with an inflatable air compartment and a fillable water compartment on a flexible base sheet. The base sheet and sheet or sheets forming the compartments can be either permanently or temporarily connected on their sides to form a pocket. The pocket can be slipped over the back of the chair to allow the inflatable pillow to serve as a head rest. However, the pillow is not easily used in a tub or at the spa, because the walls of the tub are inclined and there is no means to hold it in place. If the pillow is used on a smooth surface, where there is high wind or on a moving object, such as the deck or bow of a boat, there is danger of it blowing away, even when the water compartment is used to add weight.
It would be desirable to extend the use of such an inflatable pillow so that it can serve as a headrest while using a tub in a bath or spa or on smooth surfaces in windy locations.
It would also be desirable to allow the user to adjust the cushioning effect of an inflatable pillow having both a water compartment and an air compartment when such a pillow is used in a tub or on the bow of a moving boat.
It would also be desirable to be able to adjust the temperature of the pillow by adding water of a desired temperature.
Accordingly, one object of the present invention is to provide an improved inflatable pillow that can be used either over the back of a chair or on smooth surfaces, such as a tub, or in a spa, or on the deck or bow of a boat.
Another object of the invention is to enhance the performance of an inflatable pillow especially adapted for use in a tub or at a spa by adding a water compartment for adjustable support and temperature control.
Briefly stated, the invention comprises an improvement to an inflatable pillow comprising a generally rectangular flexible base sheet arranged to be folded about a fold line extending between its side edges, a first flexible sheet section sealed about its periphery to the base sheet on one side of the fold line to define an inflatable air compartment, a second flexible sheet section sealed about its periphery to the base sheet on the other side of the fold line to provide a fillable water compartment, an air valve communicating with the air compartment for inflating and deflating it, a closure valve communicating with the water compartment for filling and draining it and connection means to permanently or temporarily connect the folded base sheet along the side edges to form a pocket that may be slipped over the back of a chair and used to retain the inflatable pillow on the chair back, said improvement comprising one or more suction cups attached to a said sheet section so that the inflatable pillow may optionally be attached to a smooth surface, so as to serve as a combination chair pillow and a pillow for an inclined or moving smooth surface. The suction cups may be attached either to the first sheet section or to the second sheet section.
Other objects and advantages of the invention will be better understood by reference to the following description, taken in connection with the accompanying drawings, in which:
An inflatable pillow embodying the invention is shown designated generally at 10. The inflatable pillow 10 is constructed according to the teaching of my U.S. Pat. No. 6,684,429, issued Feb. 3, 2004, which is incorporated herein by reference. Referring to the plan views of
The air confining sheet section 15 and the water-containing sheet section 22 are preferably part of a single pocket sheet 14, as shown, but could also be separate sheet sections and separately attached to base sheet 12 in the same manner. Both the base sheet 12 and the pocket sheet 14 are folded up around a lateral fold line 18 of the sheets. The side edges 25, 27 are connected together to form a pocket 26 between the folded sheet members. The connections on the side edges 25, 27 may be permanent or temporary. Preferably the side edges are sealed at 25, 27, but temporary fasteners such as snap fasteners or Velcro could also be used as more fully described in my U.S. Pat. No. 6,684,429.
A removable plug 30 provides a means to fill or drain the water compartment 28. An air fill port 32 is provided to inflate the air compartment 17 to a desired comfortable inflation level, and is closed by a removable plug.
In accordance with the present invention, suction cups 34, 36 are attached to the water-containing sheet section 22 of the pocket sheet 14 on the water compartment side below and substantially equidistant from fold line 18. The suction cups are attached by any in a suitable means, such as, gluing, heat sealing, or by mechanical connection. Any suitable number of suction cups may be employed, but I have found that two are sufficient in most cases.
Suction cups 34, 36 are designed to adhere to a smooth surface such as the back of a tub, Jacuzzi, or the like so as to support the inflatable pillow. They are preferably attached to sheet section 22 on the water compartment side, but could also be attached to sheet section 15 on the air compartment side. In this case the pillow is reversed from the position shown in
The operation of the invention will be made clearer by reference to the cross sectional views of
In accordance with the improvement of the present invention, the resilience and comfort of the inflatable pillow may be enhanced by partially filling the water compartment 28. The partially filled water compartment supports and improves the comfort of the outwardly facing air compartment of the inflatable pillow 10. If desired the water compartment may be filled or partially filled with hot water from the tub to provide additional warmth in cold weather, or it may be filled or partially filled with cold water to provide cooling in hot weather.
If the suction cups are optionally attached on the air compartment side to the air confining sheet section 15, then the air compartment supports the outwardly facing water compartment, as shown in
While there has been described what is considered to be the preferred embodiment of the invention, other modifications will occur to those skilled in the art, and it is desired to secure in the appended claims all such modifications as fall within the true spirit and scope of the invention.
